WILLIAM FITTERLING, or PALISADES', cononauo.

AUTOMATIC PHOTOGRAPHIC PRINTER.

To all whom 'it may concern:

Be it known that I, WILLIAM Frr'rnnnmo, a citizen of the United States, residing at Palisades, in the. county of Mesa and State of Colorado, have invented new and useful Improvements in Automatic Photographlrinters, of which the following is a specification.

This invention relates to a photo printing apparatus of that type in which artificial light is employed to make the prints, and relates more particularly to an apparatus in which the exposure for each print is auto matically timed.

The invention has for one of its objects to improve and simplify the construction and operation, of devices of this character so as to be comparatively easy and inexpensive to manufacture and use, highly reliable and efficient in operation, and easy to manipulate for making exposures of any duration.

A further object of the invention is the employment of an automatically actuated shutter for cutting off the rays of light from the negative when the limit of the exposure is reached, thereby preventing overexposure and consequent loss and waste of prints.

Another object of the invention is to provide amotor for driving an indicator-carriage that. controls the closing of the sliut-.

ter, the carriage being adapted to actuate a brake device to arrest the motor after the shutter has been closed and the exposure completed.

A still further object is to provide a novel form of driving mechanism between the motor and carriage, whereby the latter can be easily and conveniently adjusted to effect an exposure of any desired duration.

An additional object of the invention is to provide a depressible guide rail or track on which the carriage moves while an exposure takes place so that the weight of the carriage causes the track to hold the shutter open, the track being of such length that the carriage passes off of the same at the end of the exposure to permit the track to rise and close the shutter.

A further object is the employment of a novel form of supporting structure or casing which includes a light chamber for bolding an incandescent lamp or equivalent means and which is equipped with an adjustable rest for holdingthe printing frame in operative relation to the light.

Specification of Letters Patent.

' Application flled February 26, 1907. Serial No. 359,360.

Patented Jan. 19, 1909.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts whiclnwill be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure 1 is a plan view of the apparatus. Fig. 2 is a vertical section of the apparatus. Fig. 3 is a front View with the hood removed and the printing frame rest in Qsection. Fig. 4 is a vertical sectional view. F ig. 5 is a transverse section of the motor. Fig. 6 is a detail view of a winding means for the motor. Fig. 7 is a perspective view of the carriage for holding the shutter open. Fig. 8 is a plan view of the shield or cylinder for the lamp of the device.

Similar reference characters are employed to designate similar parts throughout the several figures.

Referring to the drawings, A designates a casing or frame of the machine which is preferably of rectangular structure provided with feet 1. The casing is divided by a horizontal partition 2,. Fig. 2, into a motor compartment 3 and a light containing compa rtment4. The compartment 3 is arranged. at the top and is provided with a hinged cover 5 by means of which access to'the motor compartment is bad. As shown in Fig. 23, the upper portion of the casing is enlarged horizontally. In the compartment 4 is arranged a. sheet metal cylindrical shield dextending through the rear wall 7 of the casing and bearing against the inside of thefront wall 8. The rear end of the shield 6 is closed by a hinged door 9. At the top of the shield is a longitudinal slot 10 in which is held an incandescent lamp 11, the slot having an enlargement at one end for receiving the socket 12 of the lamp by an upward movement therethrough, whereby the lamp can be moved into the narrow portion of the slot and held from dropping by the socket. A. flexible cord conducting circuit l3 connects with the lamp .and passes out of the casing through'an operiing 1.4 in the door 9, as shown in Fig. 2. The front wall 8 is provided with an opening 15 through which the rays of light pass to the printing frame. At

the front of this opening is a shutter B for ,bers 16 havin apertures 17 that are adapted to register-wnen the shutter is fully open.

These members are fulcrumed at 18 on the front wall of the casing and a pair of toggle links 19, Fig. .3, are employed for actuating the members. Arranged over the shutter is an outwardly flaring sheet metal hood or concentrator 20 for directing the rays of light upon the printing frame. This hood 18 mounted on a rectangularframe or baseplate 21 that is removably secured on the front wall 8 of the casing.

Arranged below the hood 20 and supported on the casing A is a rest designated generally by B on which the printlng frame C is supported. The rest B" comprises a holder 21 of U-shaped cross-section which is secured to the outer ends of two parallel slides 22 that move back and forth in tubular horizontal guides 23. These guides are arranged in the casing A at the bottom corners- In the holder 21 is a leaf spring 24 anchored at one end and arranged to yieldingly hold the printing frame in position and in cotiperative relation with the hood 20. To clamp the printing frame rest B in fixed position, one of the guides 23, shown in Fig. 1, 's provided with a clamping screw 25 which binds on the slide 22 extending into the said guide. The holder 21' is open at both ends so that the printing frame C can be inserted or removed by sliding it into the holder from thev left hand end, Fig.1. The bottom edge of the printing frame is engaged by the holder and in inserting the printing frame, the spring 24 is pressed aside and firmly clamps the frame when the latter is in operative position.

The toggle links 19 for actuating the shutter B are connected with a vertically movable rod or actuator 26, Fig. 3, arranged at the front of the casing 1 and inclosed in a housing 27. On the rod 26 is a helical compression spring 28 that bears at its lower end on an abutment 29. in the housing and at its upper end on an abutment 30 formed on the rod. This spring is arranged to collapse the toggle 19 by forcing the rod 26 upwardly arid thereby closing the members 16 of the shutter. By pressing down on the rod 26 t-he toggle 19 is straightened and the members 16 thrown outwardly to cause their openings 17 to register.

The operating mechanism for controlling the openlng and closin of the shutter through the medium of the re 26 is mounted on the lid or cover 5 of the casing. On the ends .of the cover 5- are bearing brackets 31 on a guide rod 33 arranged in front of and suitablyspaced from the threaded shaft. The shaft and uide rod are each journaled on adjustable hearing screws 34 that have conical ends 35 engaging in correspondinglfy; shaped depressionsin the ends of the sha and rod. Slidably supported on the rod 33 is a carriage designated enerally. by D. This is in the nature ofa ever or body 36 slidably fulcrumed on the rod 33 that projects through a bossed hub 37. The front arm of the lever 36 is considerablylonger or heavier than the rear arm, so that the weight of the former serves to hold a threaded block on the rear arm in engagement with the threaded shaft 32. As clearly shown in Fig. 7, the'short arm 38 of the carriage D carries a sprin plate 39 on which is mountedthe threaded block 40. This block is approximately half a nut which is arranged'to engage the under side of the threaded shaft 32. By this arrangement,-the long arm 41 of the carriage can be'raised so as to disenwhich are supported a threaded shaft 32'and gage the thread of the block 40 from the shaft to permit the carriage to be freely moved on the guide rod 33 for quickly adjusting the carriage to any desired position.

While the carriage is in normal position, the w 42 is divided into a relatively long section 44 that is depressible and a fixed section or rest 45 at the left end, as shown in Fig. 1. The weightof the forward part of the carriage D holds the section 44 of the guide rail depressed and as long as the said section is depressed, the shutter B is open. ,When the carriage moves off thesection 44 to the section 45, the former immediately rises and The movable permits the shutter to close. part of the guide rail 42 is attached to an arm 46, Fig. 1, that is hinged at its rear end in bearing posts 47. The toggle actuating rod 26 passes upwardly through an opening in the cover 5 and is hingedly connected at its top end with the arm 46. A removable pin 48 or equivalent means is employed to connect the rod and arm together, and by removing this pin, the cover 5 can be swung open or closed. The guide rail 42 is supported on a rest 49 in the form of a stripsecured on the cover v5 at its front edge. K The section 45 is fixedly mounted on the rest or support 49, while, of course, the section 44 of the guide rail bears on the rest only while the carriage D is in running position. To

facilitate the adjusting of the carriage, ,a

hook shaped finger hold 5.0 is arranged on its front end, whereby the carnage can .be raised by the first finger gripping under the finger hold and While thus held in ralsedposition, the carriage can be moved laterally on. the rod 33. D15 osed in the path of the carriage is a suitab e signal which is actuated when the carriage reaches the limit of The operating shaft 32 is driven by a motor of any suitable character preferably arranged in the compartment 3 of the casing and supported on the under side of the cover 5. In the present instance, this motor designated generally by E is of the clock-work type. The various parts of the motor are mounted onv depending brackets 54 secured.

to a top plate 55 attached to the cover 5.

The motor E drives a shaft 56, Fig. 4, that is connected. by a belt and pulley transmission 57rwith the threaded carriage-actuating shaft 32. The belt of this transmission. passes through a slot 58 in the cover 5. As shown in Fig. 2, a s ring-pressed idler pulley 59 holds the belt from the transmission 57 in operative relation to the pulleys. The

, main shaft or arbor 6O of the motor is driven by a coiled spring 61 in the drum 62 and power is transmitted from the said shaft to-the pulley shaft 56 by a. suitable'train of gears, The motor springbl is wound by a pawl and ratchet device 63, the ratchet wheel of which is connected with the drum 62 for turningthe same. The ratchet wheel and drum are actuated. from outside the casing A by ashaft 64. having a pinion 65 meshing with the gear wheel 66 which latter is associated with the wheel of the ratchet device. The outer end of the shaft 64 has a crank 67 whereby the shaft can be conveniently rota ted.

In. order to stop the motor when. the carriage D reaches the end of its stroke, a brake device is employed that comprises a. disk (38 fixed; ona. shaft (59 geared by means of a pin- 10117.0, Fig. at, with one of the gear wheels ot the trainof the motor. Arranged in coloperative relation. with this disk is a shoe 71 supported on the lower end of a lever 7 2 that projects upwardly through an opening 73 in. the cover The upper end of this lever is disposed in the path of the carriage D for the purpose of being actuated by the latherwhen the carriage has passed off the deprossible-v seetionof the guide rail; 4:2, thus causing the shoe 71 to-engage the brake disk (58 and prevent the motor from unwindin when the shutter of the apparatus is closed: To start the motor, all: that is necessary is to swing the upper end of the lever or stop 72 to the right, after carriage D has been adjusted to thedesired position. To regulate the speed of the motor, aretarding device is employed for loading the motor. This devicecomprises a bell crank lever 7.4 ful crnined at 75, Fig. 4, and carrying a shoe 76- adapted to be held in frictional contact with a disk 77 on the brake shaft The frictional engagement of the shoe with the disk is controlled by an adjusting screw 7 8 extending downwardly through the cover5 and bearing against the horizontally extending arm of the bell crank lever. Ahelical extension spring 79 is connected with the bell crank lever to move the shoe 76 away from the disk 77 1 when. the adjusting screw is moved outwardly. On the shaft 69- a speed governor having centrifugally acting weights 7.9 arranged on arms 80. These arms yarecounected with; the shaft 69 to rotate therewith and they are also connected with the friction. disk 7 7 for pulling the latter into firmer engagement with the shoe 7 6. The

governor thus increases the load onthe niotor so that the speed is prevented from exceeding a. predetermined limit.

The brake lever 72 is held in set position i by a leaf spring 81. disposed at the rear thereof to have a. wiping engagement with the lever. As shown in Figs" 1 and2, the lever 72 is in normal position as when the motor is in operation. By moving the lever to. the left for setting the brake, the spring 81 frictionally holds the lever in fixed position, so that the brake cannot open except by manually shifting the lever to the right.

On the front side of the rest or support 49 for the guide rail 42, is a scale 82 having suitable divisions and denominations such as minutes and seconds. In the present in stance, the scale is suitable fora maximum exposure of fiveminutes. On the front end of the carriage I) is a pointer or index 83 which is conveniently formed as a part of the finger hold 50. 'This pointer or index is disposed to pass over the top edge of the scale when the carriage I) is in. normal position. In Fig. 3, the pointer is arranged op" positethe two-minute mark of the scale.

.V-Vhile thecarriage is-resting on the depressible portion of. the rail 42, the shutter B is To indicate the number etc osures, the carriage D is provided with a dial 84 at its frcf int,-with which is associated a hand 85 on a n a mil ed head 87 wherebyit can be conveniently enabling the photographer to kee an accurate count of the prmts that have een made.
